I finally had the opportunity to print a number of parts in ASA (similar temps to ABS) the past two days.
I have had complete success and no blown 10A fuses. The draw is greatest during the initial warm-up phase, bumping up hard against 10A (@ 110VAC today) for about 15 minutes until the bed temp is reached. However, maintaining the bed temp (inside the enclosure) for the ensuing heat soak only draws between 6 and 7 amps with Mainsail reporting 40 to 60% duty cycle.
By the time it’s actually printing at speed (300mm/s), the bed heater duty cycle is down to 20 to 40% and the current draw drops further. The highest I observed was 6.25A – although it’s entirely possible that could be exceeded for a moment at some point.
So, @sovol3d: Cheap fix. Don’t risk violating electrical safety certification; stop overfusing. Ship the 125V version with 10A fuses!
